I love cooking with fresh produce, and Mariana's is one of the best places to find inexpensive veggies and fruit. From jicama to potatoes I always manage to find something yummy.
This location is not too far from UNLV, and the prices are lower than the Albertson's and Von's nearby. The cashiers here are always friendly and humor my attempts at practicing Spanish (although they all are bilingual ).
My only complaint is that the meat area can smell very meaty, even when in the produce section. I doubt that will bother most people though!
